Abstract

The moving boundary problems include solid-liquid interface and flow front in injection mold filling. An enthalpy method model is used to predict the interface in the two-phase flow problem. The moving flow front is predicted by an assumption of average acceleration and updated boundary is corrected to meet the required volume flow rate in each time step. A two-dimensional, transient, non-newtonian and non-isothermal thermal field of a polymer in a rectangular plate is selected as study case.
